TCL2FTP is an extension library for Tcl scripts
which allows Tcl programs to perform FTP client
and gateway actions. It fully supports the FTP/FXP
protocols, is ready for use with SSL/TLS, and is
compatible with glFTPd. It can run simple FTP
commands, and it supports 25 simultaneous FTP
sessions.

CRUSH (Custom Reporting Utilities for SHell) is a
collection of tools for processing delimited-text
data from the command line or in shell scripts. It
provides utilities for aggregating, merging,
filtering, and formatting your data.

GetData is a library that provides an API to interface with dirfile databases. The dirfile database format is designed to provide a fast, scalable format for storing and reading binary, synchronously-sampled, time-ordered data. GetData was originally written for the BOOMERanG and BLAST experiments as a data format suitable for use for both quick-look and data reduction. It is now used by many other cosmological and astrophysical experiments including ACT, Planck, Spider, Keck, as well as other projects.

FriCAS is an advanced computer algebra system. Its
capabilities range from calculus (integration and
differentiation) to abstract algebra. It can plot
functions and ha san integrated help system. It is
a fork of the wh-sandbox branch of the Axiom project.

The parallel project allows for simple parallel
and distributed processing from shell scripts. In
particular, the programs accept lines of shell
code on the standard input and run these lines in
parallel. The parallelism can be either on the
local machine or on a cluster, if a small amount
of time is taken to set up SSH. Additionally, the
distributed version includes a degree of fault
tolerance.

Evergreen is a cross-platform development
environment that tries to be lightweight and
language-agnostic yet functional. It started as a
project to reimplement Rob Pike's Acme editor for
Plan 9 in Java, but has since evolved in
directions that help it deal with large codebases
and multiple projects/branches at once. Remaining
similarities include the tiled windows and the
Unix-like reliance on external programs rather
than reinventing every wheel. The major
philosophical differences include strong support
for keyboard-based editing, language-specific
functionality, and native platform UI conventions.
There are also two new guiding principles:
accepting regular expressions and output diffs.

ScanDraiD is intended to provide a minimal, robust, flexible and platform-independent library called libscan3d written in C++ for an open source 3D scanner. It also provides a user interface that implements the scanner library.
